     What I would want to do is to implement external  module functionality
in mi.

It would work similar to CALLI:
    DCL SYSPTR pModule
    DCL INSPTR pModuleCode,  pRtnIp ;
    RSLVSP  pModule,  "module name" ;
    SETIPFP  pModuleCode,  pModule ;        /* new instruction. set
instruction ptr from ptr. */
    CALLM  pModuleCode, *,  pRtnIp ;        /* new instruction. call
module. */

I realize there are external factors that prevent this, but  the concept is
one that I would like to know the feasibility of.

Steve, can you explain to me how "external module functionality" differs
from late-bound program calls?
